GAGE.

Specification of Letters Patent.

Application filed January 26, 1917. Serial No. 144,700.

To all whom it may concern:

Be it known that we, THOMAS C. BEVAN and JOHN T. lBnvAN, citizens of the United States, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Gages, of which the following is a specification.

The invention relates to gages to be used in straightening the knuckles of automobile axles.

The primary object of the present invention is to provide a gage of this character which may be adjusted to one of the true knuckles to indicate just how far it is necessary to bend the bent knuckle to its true position.

A second object of vide a gage knuckles which may be used without necessitating the removal of the Wheels from the true knuckles.

A further object the invention is to proof the invention is to provide a device of this character which.

may be easily and quickly applied in operative position and which may be adjusted to the required adjustment.

Still another object is to provide a gage for straightening bent knuckles which is applicable to any sized knuckle bore, and when applied to such bore, will be supported in an effective manner.

Another object is to provide a device of the above character which may be used for straightening the connecting arm which is carried by the knuckle as wellas to straighten the knuckle.

An additional object is to provide a gage of this character which consists of few easily assembled elements which may be replaced by new ones and which is easy to manipulate and which maybe manufactured and placed on the market at a minimum cost.

The above and other objects will fully appear in the following specification.

The invention consists of the arrangement of cooperating parts, the manner of operation and constructions which will be hereinafter fully discussed and claimed and illustrated in the accompanying drawing, in which Figure 1 is an elevation of our improved gage applied to a bent knuckle, the knuckle being shown in full lines after being bent to its true position, and

supporting rod 7 to be used in straightening bent Fig. the vertically adjustable indicating member, the extremity of the horizontally disposed carrying arm being also shown in section.

Referring to the drawing in which like characters of reference indicate like parts, the numeral 5 designates a conventional knuckle having the stub shaft 6 thereon which for the purpose of illustration it will be assumed is bent as indicated in dotted lines in Fig. 1.

The improved gage consists of a vertical which is adapted to be bore of a knuckle, which bore normally receives the king bolt and which rod terminates at its upper extremity into a horizontally disposed sleeve 8. Adjustably threaded in this horizontally disposed sleeve 8' is a set screw 9. Adjustably mounted on the vertical supporting rod 7 are cones 10 by means of which the gage may be supported rigidly in any sized knuckle bore.

Extending through the sleeve 8 is a horizontally adjustable supporting arm 11 which has a vertically disposed sleeve 12 formed upon one of its extremities and is also provided with a set screw 13. It will be seen that the horizontal arm 10 may be held in various adjusted positions by means of the set screw 9. Extending within the sleeve 12 is a tube 14 which is provided with interior screw threads 15. Extending within the tube 14 is a threaded stem 16 which has threaded engagement with the threads 15 and is provided with a head 17 upon its upper end. The lower end of this stem 16 terminates into an indicating point 18 at its lower end thereof. It will be seen that the set screw 13 retains the tube 14 in adjusted position and it will also be seen that in order to get a very slight adjustment, the knob or head 17 is rotated to move the indicating point.

In using the improved gage the supporting rod 7 is engaged in the'bore of one of the true knuckles and the cones 10 adjusted to the required position to firmly support the supporting rod 7, and the horizontal arm 11 is adjusted horizontally to the end of the knuckle. The threaded stem 16 is now adjusted vertically to engage the point 18 on the stub shaft of the true knuckle. After these adjustments have been secured, the supporting rod 7 is engaged in the bore of the bent knuckle and this bent shaft is now supported in the Patented July 16, 1918.

2 is a vertical sectional view through,

bent until it engages the point '18, as clearly shown in Fig. 1. This figure also shows the bent shaft indotted lines. 7

It Will also be manifest that this improve d gage may be used in the same manner to" straighten the connecting arms which are carried by the knuckles and which are connected With the steering mechanism. v

While the above disclosure'embodies what is now believed to be thepreferred embodiment of invention, it is to be understood }that the same is susceptible to various modificag tions and alterations that may be embodied in the herewith appended claims.

What is claimed, is;

1. In a. knuckle straightening gage, 'a'supporting rod adapted to be applied to the bore of a knuckle, a horizontally disposed sleeve carried thereby, an arm adjustably mounted in the sleeve and also provided a horizontal rod slidably adjustable in said bearing, a vertically*disposed sleeve formed on one end of said horizontal rod, a tube slidably adjustable in said sleeve, and a gagestem extended through said sleeve and threadedly engaged therewith.-
